This error is misleading because it doesn't tell you what you have
actually done wrong, so there is a bug in the way that errors are
handled which I'll take down and address at some stage.

Your issue is that you are using the start/2 call which is intended to
be used by the direct driver, not the network driver.

If you want to use plain jane networked AMQP, you need to supply the
hostname as a third argument, i.e.

Connection = amqp_connection:start(User, Password, "hostname").
